Title: Sub Sahara Africa


1
The Physical Geography of Africa
2
North Africa
  • When the Egyptians constructed the Aswan High
    Dam, they also built the largest human-made lake
    in the world-Lake Nasser. Lake Nasser is over
    300 miles long!

3
Mountains in North Africa
  • The Atlas Mountains are found in Morocco and
    Algeria

4
The Atlas Mountains of Morocco and Algeria
  • The Atlas mountain range is the longest range
    in Africa. They cause a great amount of rainfall
    on the northern coast . It is along this
    northern coast where most of North Africas
    population lives.

5
Rivers of North Africa
  • The Nile River- Egypt
  • The Nile River is the longest river in the world
    (4,145 miles long) It begins near the equator
    and empties into the Mediterranean Sea.
  • The river floods annually creating a very fertile
    strip of land along its banks and in its flood
    plain.
  • 90 of Egypts population lives along the Nile
    River.

7
Africa South of the Sahara
8
Sub Saharan Africa
  • -only region in the world to lay almost entirely
    in the tropics

9
Population Patterns
  • worlds fastest growing population.
  • youngest population- nearly 50 of its people are
    15 years old or younger.
  • more than 2,000 different cultural groups, 800
    languages and hundreds of dialects.

10
Population Density of Africa
11
The Environment
  • Droughts, over-farming and overgrazing have
    contributed to the spread of desert areas
  • Sahel-region between the Sahara and the rain
    forests near the western African coast

Physical Geography
  • The eastern and southern areas are called High
    Africa
  • the elevation is generally more than 3,000 feet
    above sea level.
  • The Equator runs through the middle of Africa.
    90 of the continent lies within the tropics.

15
Major Land Features
  • Mountains and Highlands
  • The Great Rift Valley
  • Plateaus
  • Rivers and Waterfalls
  • Lakes Victoria

16
Mountains and Highlands
Eastern Highlands
Ruwenzori Mountains
Volcanic Peaks
Drakensberg Mtns
17
The Ruwenzori Mountains of Uganda
  • The 'Mountains of the Moon' lie along the western
    border of Uganda, on the border with the DRC.
  • The Ruwenzori Mountains region became a National
    Park in 1991.

18
Mount Stanley
19
  • 16763 ft (5109 m)    
  • Highest point in Congo and Uganda
  • Major Peaks
  • Margherita Peak    16763 ft Alexandra Peak  
     16703 ft
  • Albert Peak     16690 ft
  • Location Ruwenzori Mountains, Congo-Uganda
    border

20
The Drakensberg Mountains
  • in South Africa, located in the heart of the Zulu
    kingdom.
  • Dragons Mountain

21
Drakensberg Mountains
22
Drakensberg Mountains Policemens Helmets
23
Tugela Falls
  • world's second highest waterfall.
  • The total drop is 3,110 feet

24
3 of the 5 cascades can be seen here
25
Volcanic Peaks of Kenya and Tanzania
  • Mount Kenya is the 2nd highest mountain in
    Africa. It is an extinct volcano.
  • It dominates the Central Kenyan highlands,
    towering just seventy miles north of Nairobi, and
    ten miles south of the Equator.

26
Mount Kilimanjaro
  • Africas highest mountain
  • Like Mt. Kenya, is an inactive volcano
  • Located in Tanzania

27
The Great Rift Valley
  • Stretches from the Jordan River to the Zambezi
    River in Mozambique.
  • created by great tectonic forces below the
    earths surface that has cracked the surface.

28

29
  • Map of East Africa showing some of the
    historically active volcanoes(red triangles) and
    the Afar Triangle (shaded, center) -- a so-called
    triple junction (or triple point), where three
    plates are pulling away from one another the
    Arabian Plate, and the two parts of the African
    Plate (the Nubian and the Somalian) splitting
    along the East African Rift Zone.

30
Serengeti Plain
  • Grassland in Northern Tanzania and southern Kenya
  • Ideal for grazing animals

31
Rivers
  • Six great rivers run through Africa
  • Nile River
  • Niger River
  • Zaire River
  • Zambezi River
  • Limpopo
  • Orange River

32
Postcards From the Niger River
33
The Zaire River
  • 2nd longest river in Africa. It flows through
    tropical rainforest and grasslands to the
    Atlantic Ocean.
  • It flows north and crosses the Equator where it
    then drops down the mighty Boyoma Falls, a
    spectacular waterfall.

34
Also called the Congo River

35
Zambezi River
  • Africas 4th largest river system
  • runs through 6 countries from central Africa to
    Indian Ocean.
  • less developed than others in terms of human
    settlement and many areas along its banks enjoy
    protected status.

36

37
The Limpopo River
  • The enormous Limpopo Heartland spans 3 diverse
    countries of Mozambique, South Africa and
    Zimbabwe
  • includes South Africa's popular Kruger National
    Park.

38
Kruger National Park
  • more wildlife species than any other game
    sanctuary in Africa, including 10,000 elephants

39
The Orange River
  • rises in the Lesotho Highlands and flows west
    across the Republic of South Africa.
  • It passes the South edge of the Kalahari Desert,
    and winds through the Namib Desert before
    draining into the Atlantic Ocean in South Africa.
    It forms the border between South Africa and
    Namibia.

Plateaus
  • Africa is a continent of plateaus
  • The coastal plains extend only about 20 miles
    inland and a sudden rise in land occurs. This
    extreme rise in the topography has made access
    into the interior very difficult.
  • highest overall elevation of the continents with
    the average of sub-Sahara Africa at 2,000 feet
    above sea level.
